reload a page in django using ajax?
I am building a messaging app and i want to reload my page every 1 minute so that the user can see new messages if there is some i know how to do it in html but i wanna use ajax(i am not so good in it) to reload the page. here is my views.py: class MessagesView(LoginRequiredMixin,View): def get(self, request, chat_id): try: chat = Chat.objects.get(id=chat_id) if request.user in chat.members.all(): chat.message_set.filter(is_readed=False).exclude(author=request.user).update(is_readed=True) else: chat = None except Chat.DoesNotExist: chat = None return render( request, 'users/messages.html', { 'user_profile': request.user, 'chat': chat, 'form': MessageForm() } ) def post(self, request, chat_id): form = MessageForm(data=request.POST) if form.is_valid(): message = form.save(commit=False) message.chat_id = chat_id message.author = request.user message.save() return redirect(reverse('messages', kwargs={'chat_id': chat_id})) and my template is: {% extends 'profile/base.html' %} {% load tz %} {% block title %} Messages {% endblock %} {% block head %} <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <style> #form { position: fixed; bottom: 0; background-color:#f1f1f1; } .container { border: 1px solid #dedede; background-color: #f1f1f1; border-radius: 5px; padding: 1px; margin: 1px 0; } .container::after { content: ""; clear: both; display: table; } .darker { border-color: #ccc; background-color:#ddd; } .container img { float: left; max-width: 40px; height:40px; width: … -

Get Dynamic Select option in Clone Node using Javscript
I'm trying to create a form where I'm giving dynamic select option i.e one select option will depend on another select option, as you can see in the Image below, if Gender is male and Child the age group is between 1-18 similarly for Adult its greater than 18. And By clicking Add member I'm cloning the whole Person div, but the script is not working for the cloned node and I'm only getting AgeGroup of the 1st div whose clone is created. I'm trying to build this form in Django if that helps. My code: document.getElementById('addMember').onclick = function() { var addOnDiv = document.getElementById('addon'); var clonedNode = addOnDiv.querySelector('.memberBody').cloneNode(true); addOnDiv.appendChild( clonedNode ); } ## for select $("select").change(function() { var selectedVal = $('#type').val(); var selectedGender = $('#gender').val(); console.log(selectedGender); console.log(selectedVal); if('Child' === selectedVal){ var childGroup = '<select name="h_ageGroup" class="custom-select"> <option value="" disabled="disabled" selected="selected">Choose option</option>........</select>'; $('#selectList').html(childGroup); } if('Adult' === selectedVal ){ var childGroup = '<select name="h_ageGroup" class="custom-select"> <option value="" disabled="disabled" selected="selected">Choose option</option> <option value=">18 Years"> >18 Years </option></select>'; $('#selectList').html(childGroup); } }); How can I get dynamic select on my cloned node too. Is there any other way through which I can achieve this ? -

Django | Same form multiple times on the same template
I have a project with a model called "List," and a model called "ListItem." There are multiple list items to each list. Here's what I'd like to do. I'd like the user to be able to create a new list with as many items as they deem necessary on one form. Here's the logic I have so far: models.py: class List(models.Model): team = models.ForeignKey(Team, on_delete=models.CASCADE) name = models.CharField(max_length=50) def __str__(self): return self.name class ListItem(models.Model): team_list = models.ForeignKey(List, on_delete=models.CASCADE) content = models.TextField() index = models.IntegerField() def __str__(self): return f"{self.team_list} [{self.index}]" forms.py: class NewListForm(forms.ModelForm): name = forms.CharField(max_length=50, label='Card Name') team = forms.ModelChoiceField(queryset=models.Team.objects.all()) class Meta: model = models.List fields = ['name', 'team'] class NewListItemForm(forms.ModelForm): content = forms.CharField(widget=forms.Textarea, label='Item', required=True) class Meta: model = models.ListItem fields = ['content'] views.py: def new_list(request): context = { 'title': 'New List', 'list_form': NewListForm, 'list_item_form': NewListItemForm, } if request.method == 'POST': list_form = NewListForm(request.POST) list_item_form = NewListItemForm(request.POST) if list_form.is_valid() and list_item_form.is_valid(): list_instance = list_form.save() list_item_instance = list_item_form.save(commit=False) list_item_instance.team_list = list_instance list_item_instance.index = 1 list_item_instance.save() messages.success(request, "List has been created!") return redirect('home') else: messages.error(request, "That list name is already taken") return render(request, 'lists/new_list.html', context) This works for creating 1 list and just 1 item.

Django How to reuse a URL and View based on an input or state?
I currently have a url and a view to display my objects. Is it possible to create a new URL with the same view then just change the filter of objects without creating a new view?

Contacting another WebSocket server from inside Django Channels
I have two websocket servers, call them Main and Worker, and this is the desired workflow: Client sends message to Main Main sends message to Worker Worker responds to Main Main responds to Client Is this doable? I couldn't find any WS client functionality in Channels. I tried naively to do this (in consumers.py): import websockets class SampleConsumer(AsyncWebsocketConsumer): async def receive(self, text_data): async with websockets.connect(url) as worker_ws: await worker_ws.send(json.dumps({ 'to': 'Worker' })) result = json.loads(await worker_ws.recv()) await self.send(text_data=json.dumps({ 'to': 'Client' }) However, it seems that the with section blocks (Main doesn't seem to accept any further messages until the response is received from Worker). I suspect it is because websockets runs its own loop, but I don't know for sure. The response { "to": "Client" } does not need to be here, I would be okay even if it is in a different method, as long as it triggers when the response from Worker is received. Is there a way to do this, or am I barking up the wrong tree? If there is no way to do this, I was thinking of having a thread (or process? or a separate application?) that communicates with Worker, and uses channel_layer to … -
Is there a good way to deal with multiple forms and models in Django?
I'm building an app in which I have a model with several manytomany fields and some foreignkey fields, and I need a view that allows me to create all in one page and let me enter multiply times for the manytomanyfields, but I don't know how to deal with a lot of forms in the same page/view. main model class Client(models.Model): company_name = models.CharField(max_length=255, blank=True, null=True) payment_method = models.CharField(max_length=64, null=True, blank=True) owner = models.CharField(max_length=100, blank=True, null=True) operation = models.CharField(max_length=50, blank=True, null=True) value = models.DecimalField(max_digits=8, decimal_places=2, null=True, blank=True) currency = models.CharField(max_length=55, null=True, blank=True) address = models.ManyToManyField(Address, blank=True) contact = models.ManyToManyField(Contact, blank=True) relationship = models.ManyToManyField(Relationship, blank=True) attachment = models.ManyToManyField(Attachment, blank=True) billing = models.ForeignKey(Billing, null=True, blank=True, on_delete=models.CASCADE) delivery = models.ForeignKey(Delivery, null=True, blank=True, on_delete=models.CASCADE) author = models.ForeignKey(User, on_delete=models.DO_NOTHING, blank=True, null=True) note = models.TextField(blank=True, null=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.company_name others models class Address(models.Model): address = models.CharField(max_length=256, null=True, blank=True) number = models.PositiveIntegerField(null=True, blank=True) district = models.CharField(max_length=32, null=True, blank=True) city = models.CharField(max_length=32, null=True, blank=True) country = models.CharField(choices=COUNTRY_CHOICES, max_length=64, null=True, blank=True) def __str__(self): return self.address class Contact(models.Model): name = models.CharField(max_length=256, blank=False, null=True) sector = models.CharField(max_length=64, blank=True, null=True) email = models.EmailField(max_length=256, blank=True, null=True) phone = PhoneField(blank=True, null=True) cellphone = PhoneField(blank=True, null=True) role = … -

Django + OWASP ZAP Cross Site Scripting (Reflected) - Is the value attribute of an HTML input tag a risk?
In my Django project, I have a search input in the navbar across most pages on my site. I'm a beginner to OWASP ZAP. After running the scan, one of the high priority alerts (red flag icon) raised was "Cross Site Scripting (Reflected)". In my case, this is my website search form: <form method="GET" id="searchForm"> <input type="text" name="q" id="searchQuery" placeholder="Search..." autocomplete="off" maxlength="100" required=""> </form> if someone searches for javascript:alert(1); in the search box, the value= attribute contains the same. <form method="GET" id="searchForm"> <input type="text" name="q" value="javascript:alert(1);" id="searchQuery" placeholder="Search..." autocomplete="off" maxlength="100" required=""> </form> Is this is a potentially vulnerability or is the input is being sanitized by Django? This form is created using a Django forms.ModelForm: class SiteSearchForm(forms.ModelForm): class Meta: model = Search fields = ('q',) -
How to prepopulate tabularInline fields with different values per-row
I have a ModelAdmin class with an inline of type TabularInline. What I would like is for each row of the TabularInline. What I need to do is to pre-select the select boxes with the available languages so each of them will have one of the languages as a selected value (e.g. row1: English, row2:Arabic, row3: Français, row4: Espanol). Please note that the number of rows is generated based on the count of the available languages. Any suggestions would be appreciated.

Django Two Factor Auth with custom login
I am trying to add two factor login using the @otp_required decorator from Django Two-Factor Authentication into my custom login.

Django Admin login not working after model change
I changed the username field to email, following this guide. Everything works so far, except for Django Admin Website, which worked before like a charm. No matter what I enter it always displays "Please enter the correct email address and password for a staff account. Note that both fields may be case-sensitive.". This is odd, as I am still able -from my separate frontend- to add and login users. Just the ones created via createsuperuser don't work properly. I went to the shell and it stated the following: >>> from user.models import User >>> User.objects.get(id=1) <User: Firstname Lastname> >>> me = User.objects.get(id=1) >>> me.password 'pbkdf2_sha256$216000$XTRS1jTuNQWA$rvRCMxeYAJVaL1SftNjXBYCxlMiRnHs9uopq4OMh6gM=' >>> me.email 'me@test.test' >>> me.username >>> me.is_staff True >>> me.is_superuser True >>> me.is_active True So this seems to work. But when I do the authenticate method for those credentials, nothing happens. My model looks basically like this and worked before the change: class User(AbstractUser): username = None email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] objects = CustomUserManager() I tried deleting the database and reading the user, I tried different passwords and usernames (mail addresses). -
trouble with django on git bash. command not found

Django createsuperuser command not working after switching from username to email
So I changed the Django username field to 'email', which is documented as completely legal here, but after this, the createsuperuser method doesn't work. Of cause I have added the Auth model to my settings and it worked before. This is basically my model currently: class User(AbstractUser): username = None email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] After migrating the change createsuperuser throws this after every input is entered: XXX\django\contrib\auth\management\commands\createsuperuser.py", line 189, in handle self.UserModel._default_manager.db_manager(database).create_superuser(**user_data) TypeError: create_superuser() missing 1 required positional argument: 'username' I tried moving around this with a custom manager, but it threw new problems plus I would really would like to avoid this. Furthermore, I looked at the source code of the method, but couldn't figure out where this could go wrong. I also reset and deleted the database without luck. -

localhost vs. 127.0.0.1 in regards to CSS
So I've seen a few posts about the differences between localhost and 127.0.0.1 but nothing specifically regarding my question. I am currently creating a Django application which, when run, starts the application on 127.0.0.1:8000. My problem involves updating my CSS files and not always seeing changes when I refresh. Sometimes the changes will display on one of the two but not the other and was curious as to why this may be? I do currently have multiple CSS files as well as bootstrap files which I have downloaded the libraries for. Any general feedback on why these changes occur on one of the two but not the other would be appreciated! -
Django objects.filter vs objects.all
I have a question regarding the filter() and all() methods of django objects. It is not a question which one of the two is preferred, I just noticed an odd (to me) behavior. Because, as it is laid out in Django ORM - objects.filter() vs. objects.all().filter() - which one is preferred? in Django src, both ways should return the same (they both reference the chain() method): See: https://github.com/django/django/blob/0963f184abd96800b76b19a6a181e1b544c7fafe/django/db/models/query.py#L928 And: https://github.com/django/django/blob/0963f184abd96800b76b19a6a181e1b544c7fafe/django/db/models/query.py#L951 So the filter() and all() method should return the same objects. But I recently discovered the following behavior: MyModel.objects.all()[0].update(name="Test") # --> $: AttributeError: type object 'MyModel' has no attribute 'update' # And to check if it indeed has no update method: MyModel.objects.all[0].__dir__() # --> no update() method in returned dictionary but a save method So while above code raises Error, line below would work: MyModel.objects.all()[0].name = "Test" MyModel.objects.all()[0].save() However, if the same object is retrieved by the filter() method, it has the update() method. Why do I get the same object both times but with seemingly different methods added to it? -
